Keyless entry + relay question

Hi, this is my first time wiring a keyless entry system. I own a 89 RX-7 with stock power locks. This is an aftermarket door lock motor that the last owner installed.

I traced the door lock motor wires from the door into the driver's side kick panel.
These 2 wires (blue and green)
 

connects to 

another strand of wires (didn't take them apart, but assuming they are the power, ground, etc.) these 2 relays...

I asked around and some suggested that i should wire my keyless entry system with the Actuators/reverse polarity set up.

Should i wire my keyless entry system into these relays? If i can wire into these relays, which wires should i connect? OR should i just get 2 new relays, break these wires, and then do the actutators/ reverse polarity set up and connect the "to door lock motor" wires BACK to these 2 relays and let them work as they do now?

don't know why pictures does not show up...

and this one
